we recommend you do a few things before putting
it away. This will make it easier when you want to
use the machine again and will also prevent per-
manent damage to the engine.
• Storage
Before putting the machine away:
– Empty the fuel tank.
– Start the engine and run it idle until it comes to a
halt, so that it uses up all the fuel that is left in the
carburettor.
– Wait for the engine to cool down and remove the
spark plug
– Pour a teaspoon of fresh oil into the spark plug
hole.
– Pull the starter rope several times to deliver oil to
the cylinder.
– Replace the spark plug with the piston in the
dead end upper position (visible from the spark
plug slot when the piston is at maximum stroke).

– Pull the starter rope a few times to eliminate ex-
cess oil.
